t56 behind an olds how to
My input shaft was effectively shortened 1/2" because of the adapter plate, the plate goes in between the front of the trans (you cut down the LT1 snout) and the bellhousing, The LS input is like 3/4" longer so i had to tap the bronze bushing deeper into the sleeve just a tad, but I think it has great alignment, and I didn't have to drill the crank which is awesome!
no pics yet but i ran a line from the clutch master to the TO bearing bled it and got it all set up, engine back in and the clutch disengages well and has good pedal feel. im using a 98-02 camaro master cylinder with a bracket that bolts between the firewall and brake master. also using a s10 remote fluid reservoir.

I got it all done, no test drives yet but pedal pressure and throw are great. I'll try to get a Parts list and mods into one post.

Looking forward to a parts list as i am about to pick up a t56 to be putting in my Vista Cruiser. I am also going to be picking up a 455 that has been setup for a manual setup, meaning drilled out, did you have that crank or an automatic crank?
Jeremiah, the pic of the bushing in the crank, that looks like a steel crank.
Is that a 455 or a 425 engine?
I see it has "G" heads, just wondering.
Gene
Also Young Olds what is happening with the '62 Cutlass?

My 62 drag project has been on the back burner for quite some time now, still have every intention of finishing.
I found that the mounting surface where you bolt your tranny mount on a t56 is a 1/2" further away from the output shaft as a th350. I went to a Chevy style tubular crossmember and dropped the mounting point a 1/2" to compensate. I had done the stock stamped crossmember but my tranny bounced while I was driving. The tubular one is nice and stiff
parts/mods list for t56
idk if i remembered everything so let me know.
t56 transmision, i paid $1000, seem to go for $1000-1500 in my area.
dorman oil lite bushing, 690-035. fits undrilled auto crank, sbo and bbo. a few bucks
mcleod bellhousing 8770-10, sfi rated bop/chevy pattern. this placed the t56 input shaft perfect with the pilot bushing. approx. $540
ram hydraulic throw out bearing 78125, for muncie/saginaw retrofit. comes with guide studs made to replace one of the retainer/collar bolts on a muncie/ saginaw. approx. $150
98-02 camaro/firebird clutch master cylinder approx. $60
detroit speed master cylinder bracket 070430, sandwiches between brake master and firewall. approx. $30
clutch master remote reservoir from s10, dont remember what year just walked around the junkyard till i found one that mounted flat on the firewall. i think i paid $10
72 cutlass 4 speed clutch kit. approx. $160
misc. hydraulic line, $10 ish
shop time for the tranny collar to get sleeved was a bit over $100 if i remember correctly, $90 an hour shop rate.
all together about $2100 to do it the way i did.
for mods i had to make a bracket to locate the guide stud for the throw out bearing, pictured on first page post #38. i also had to have the throwout bearing collar on the transmission sleeved to the size of a muncie so i could use a more common throw out bearing. I originally modified my factory stamped crossmember, had to be dropped to compensate for difference in mounting pad heights, described in post #50, but it bounced while driving so i bought one for a first gen chevelle which is basically the same just tubular. in my 66 i had to drill all new holes rearward of the original ones. may not be a problem for cars drilled for th400 but idk.

update on my set up
the stock 98-02 camaro master cylinder does not push enough fluid to fully disengage the clutch with my throwout bearing. normal driving is just fine but when i get on it real hard i have to let up on the gas to shift and cant rev it way up, kinda have to short shift. I will be going to a 1" bore master to hopefully aleviate the problem

i have it shimmed to rams specs, watching from underneat the car with someone pushing the pedal you can see that it doesnt quite open all the way. there is a travel mod the camaro guys do but i have a bunch of pedal travel now and dont want more. im going to pick up a 1" bore master, should get a full disengage with the same or less pedal travel.
The bell housing I bought is made to bolt to bop and Chevy as well as having a spot for a starter on both side. I had zero issues other than you have to go starter nose in first vs just straight up.
I do recal that number when doing my research on bellhousings. I was calling the manufacturers to ask the depth of the bell and the 8770 was right for my setup. Here it is on summit http://www.summitracing.com/parts/mcl-8770-10
